如何在玩家精灵（图像）和简单盒子之间添加碰撞

Question

我正在制作一个简单的马里奥游戏。我只是想要一个角色，显然马里奥会跳入一组碰撞框，这些碰撞框将显示一个数学问题的答案。到目前为止，我已经设法将重力和水平碰撞放在一起，但我似乎无法解决如何让我的角色在与简单的盒子/矩形碰撞时给我一个输出。到目前为止，这是我的代码：

pygame.display.set_caption("Super Mario Bros")
myfont = pygame.font.SysFont("Comic Sans MS", 100)

pygame.mixer.music.play(-1)

我在不同的 python 文件中有一个播放器和碰撞子类，命名为：块和播放器，它只做碰撞和简单的重力等。

感谢您的帮助，正如我所说，我很新，所以任何解释或帮助将不胜感激。

这是我的其他代码： 我的播放器.py： 导入pygame

class Player:
    def __init__(self, x, y):
        self.x=x
        self.y=y
        self.width=32
        self.height=32
        self.velocity=0
        self.falling=True
        self.onGround=False

        self.images = pygame.image.load('resources/sprite.png')
        self.images = pygame.transform.scale(self.images, (35, 35))
    def jump(self):
        if (self.onGround == False):
            return
        self.velocity = 14
        self.onGround = False

    def detectCollisions(self, x1, y1, w1, h1, x2, y2, w2, h2):
        if (x2 + w2 > x1 >= x2 and y2 + h2 >= y1 >= y2):
            return True
        elif (x2 + w2 >= x1 + w1 > x2 and y2 + h2 >= y1 >= y2):
            return True
        elif (x2 + w2 >= x1 >= x2 and y2 + h2 >= y1 + h1 >= y2):
            return True
        elif (x2 + w2 >= x1 + w1 >= x2 and y2 + h2 >= y1 + h1 >= y2):
            return True
        else:
            return False

    def update(self, gravity, blockList):
        if (self.velocity < 0):
            self.falling = True
        collision = False
        blockX,blockY = 0,0
        for block in  blockList:
            collision = self.detectCollisions(self.x, self.y, self.width, self.height, block.x, block.y, block.width, block.height)
            if (collision == True):
                blockX=block.x
                blockY=block.y
                break
        if (collision == True):
            if (self.falling == True):
                self.falling = False
                self.onGround = True
                self.velocity = 0
                self.y = blockY - self.height

        if (self.onGround == False):
            self.velocity += gravity

        self.y-=self.velocity

    def render(self, window):
        window.blit(self.images, (self.x, self.y))

    def render1(self, collision):
        if (collision==True):
            pygame.draw.rect(window,red,(self.x,self.y,self.width,self.height))
        else:
            pygame.draw.rect(window,black,(self.x,self.y,self.width,self.height))

还有block.py： 导入pygame

class Block:
    def __init__(self, x, y):
        self.x=x
        self.y=y
        self.width=32
        self.height=32

    def render(self, window):
        pygame.draw.rect(window, (255,174,0),(self.x, self.y, self.width, self.height))

我不知道图片和盒子的尺寸，所以我写了一些随机尺寸。希望它会帮助你。 这是代码：

simplebox_width = 20 #pixels
simplebox_height = 20

image_width = 50
image_height = 250

image_x_coord = 100 #coords
image_y_coord = 200

simplebox_x_coord = 140
simplebox_y_coord = 250

image_x_side = range(image_x_coord, image_x_coord+image_width)
image_y_side = range(image_y_coord, image_y_coord+image_height)

simplebox_x_side = range(simplebox_x_coord, simplebox_x_coord+simplebox_width)
simplebox_y_side = range(simplebox_y_coord, simplebox_y_coord+simplebox_height)

for x in image_x_side:
    if x in simplebox_x_side:
        for y in image_y_side:
            if y in simplebox_y_side:
                collision = True
    else:
        collision = False

print collision
